The Mona Lisa has been the subject of awe and fascination for centuries, with experts from around the world desperate to solve the mystery behind her iconic, enigmatic smile. Now, thanks to X-ray technology, scientists have begun to uncover the secrets of Leonardo da Vinci’s legendary portrait, and explain how he was able to create something so mind-bending with just a few strokes of a brush. The research, published in the Journal of the American Chemical Society on Wednesday, suggests that the Italian Renaissance master may have been in a particularly inventive mood when set about crafting the piece in the early 16th century. "He was someone who loved to experiment, and each of his paintings is completely different technically," Victor Gonzalez, the study's lead author, told the Associated Press.. Gonzalez, who has studied the chemical compositions of dozens of works by Leonardo and other artists, discovered that there was something special about the paint used for the Mona Lisa. Specifically, the researchers found a rare compound, called plumbonacrite, in Leonardo's first layer of paint. The discovery confirmed that Leonardo most likely used lead oxide powder to thicken and help dry his paint as he began working on the portrait. He is thought to have dried the powder, which has an orange colour, in linseed or walnut oil by heating the mixture to make a thicker, faster-drying paste. "What you will obtain is an oil that has a very nice golden colour," Gonzalez said. "It flows more like honey." Carmen Bambach, a specialist in Italian art and curator at New York's Metropolitan Museum of Art, who was not involved in the study, called the research "very exciting". She emphasised that any scientifically proven new insights into Leonardo's painting techniques are "extremely important news for the art world and our larger global society." Finding plumbonacrite in the Mona Lisa attests "to Leonardo's spirit of passionate and constant experimentation as a painter—it is what renders him timeless and modern," Bambach said. The paint fragment Gonzalez and his team analysed for their study was taken from the base layer of the painting and was barely visible to the naked eye. It was no larger than the diameter of a human hair, and came from the top right-hand edge of the picture that now takes pride of place in Paris’s Louvre Museum. The scientists peered into the sample’s atomic structure using X-rays in a synchrotron – a large machine that accelerates particles to almost the speed of light. This allowed them to unravel the speck's chemical makeup and detect the plumbonacrite. The compound is a byproduct of lead oxide, allowing the researchers to say with more certainty that Leonardo likely used the powder in his paint recipe. "Plumbonacrite is really a fingerprint of his recipe," Gonzalez said. "It's the first time we can actually chemically confirm it." After Leonardo, Dutch master Rembrandt may have used a similar recipe when he was painting in the 17th century; Gonzalez and other researchers have previously found plumbonacrite in his work, too. "It tells us also that those recipes were passed on for centuries," Gonzalez said. "It was a very good recipe." Still, the ‘Mona Lisa’—said by the Louvre to be a portrait of Lisa Gherardini, the wife of a Florentine silk merchant—and other works by Leonardo still have other secrets to tell. "There are plenty, plenty more things to discover, for sure,” Gonzalez said. “We are barely scratching the surface.” Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Novak Djokovic has lost the 2023 Men's Wimbledon final to Spanish underdog Carlos Alcaraz in a thoroughly thrilling match at SW19, to end the Serbian's domination of the event. 20-year-old Alcaraz went the full five sets with the outspoken tennis great, who felt for possibly the first time in his career, crowds majorly turn against him in favour of his younger opponent. Djokovic has seven men's Wimbledon singles titles to his name but couldn't add an eighth to his record of accomplishments as the plucky and dynamic Alcaraz claimed just his second grand slam of his fledgling career. Sign up to our free Indy100 weekly newsletter Djokovic did spark controversy during the match when after losing a game, smashed his racquet off one of the net posts, destroying the racquet in the process and leaving a significant dent in the post. This frustration didn't help Djokovic as Alcaraz managed to win Wimbledon for the first time by 3 sets to 2, thus toppling the great Serbian from his perch in an epic 4 plus hour match.

UK Research and Innovation (UKRI) has announced £50 million in funding to develop trustworthy and secure artificial intelligence (AI) that can help solve major challenges. The investment, which will bring experts across different fields together, was revealed during this year’s London Tech Week. As part of the package, £31 million has been awarded to a group called Responsible AI UK (www.rai.ac.uk), led by the University of Southampton. Its aim is to create a UK and international research and innovation ecosystem for responsible and trustworthy AI that will be responsive to the needs of society. AI tends to be looked at by the tech community as AI that has been thoroughly tested Professor Gopal Ramchurn Led by Professor Gopal Ramchurn, the consortium will help people understand what responsible and trustworthy AI is, how to develop it and build it into existing systems, and the impacts it will have on society. Explaining what trustworthy AI means, Prof Ramchurn said: “Trustworthy AI tends to be looked at from a very technical perspective – ie it is tested and validated in well-defined settings. “However, that doesn’t mean it will be trusted by the public, government, and industry.” He added: “AI tends to be looked at by the tech community as AI that has been thoroughly tested. “It can be AI that is trustworthy by the technical functionality of the application and the particular closed environments it has been tested in, but it is not trusted because maybe it uses personal data, you know, uses your personal data in ways that you would not want it to do.” In addition, £2 million will be awarded to 42 projects to carry out feasibility studies in businesses as part of the BridgeAI programme. These will speed up the adoption of trusted and responsible AI and Machine Learning (ML) technologies. The projects will look at developing a range of tools to facilitate assessment of AI technologies, and successful ones will go on to receive a share of an additional £19 million to develop these solutions further. A further £13 million will be used to fund 13 projects to help the UK meet its net zero targets. Universities across the UK, from Edinburgh to Aberystwyth, and Leicester to Southampton, will lead these projects. The UK’s expertise in the field of AI is a major asset to the country and will help develop the science and technology that will shape the fabric of many areas of our lives Kedar Pandya, the Engineering and Physical Sciences Research Council UKRI has also awarded two new Turing AI World Leading Researcher Fellowships, to Professor Michael Bronstein and Professor Alison Noble, both based at the University of Oxford. Kedar Pandya, executive director, Cross-Council Programmes at the Engineering and Physical Sciences Research Council, said: “The UK’s expertise in the field of AI is a major asset to the country and will help develop the science and technology that will shape the fabric of many areas of our lives. “That is why UKRI is continuing to invest in the people and organisations that will have wide-ranging benefit. “For this to be successful we must invest in research and systems in which we can have trust and confidence, and ensure these considerations are integrated in all aspects of the work as it progresses. “The projects and grants announced today will help us achieve this goal.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live ‘Last Beatles record’ was created using AI, says Paul McCartney Put ‘public good’ at heart of AI and new tech, Starmer to say Ukrainian schoolboy to buy home for his mother after selling Minecraft server
